Answer: The sentence that contains correct word usage is "The council voted to uphold the education budget as planned".
Step-by-step explanation: In the sentence "The council voted to uphold the education budget as planned", "council" has been used as a noun and it makes reference to a body of people who meet regularly to discuss and vote about public affairs. Therefore, in this case, the use of the word "council" is related to the context of this sentence (a public affair is being discussed: the education budget). On the other hand, sentences 1 and 3 include the word "counsel" when "council" should have been used instead. Furthermore, sentence 2 also shows incorrect word usage as it uses "council" instead of "counsel".
